[[ like shopt is a bash feature, so you should use a shebang in your script or run it with bash – muru Sep 15 '17 at 13:46
'shebang' == a first line in the script with the content #!/bin/bash – sudodus Sep 15 '17 at 13:48
@muru even by adding #!/bin/bash .. m getting same error – Gaurav Singh Sep 15 '17 at 13:53
@GauravSingh how are you running the script? – muru Sep 15 '17 at 13:53
@muru sh demo.sh – Gaurav Singh Sep 15 '17 at 13:54

See https://askubuntu.com/questions/22910/what-is-the-difference-between-and-sh-to-run-a-script about that you should run with bash demo.sh or ./demo.sh – muru Sep 15 '17 at 13:56
@muru . Nice :) – Gaurav Singh Sep 15 '17 at 14:01
